Common Characteristics of Multiple Disabilities:
Students with multiple disabilities generally have specific characteristics related to their Intellectual Functioning, Adaptive Skills, Motor Development, Sensory Functioning, and Communications Skills. Most students with multiple disabilities have many impairments in intellectual functioning. Students vary widely in their academic abilities. Adaptive skills include conceptual, social, and practical competencies for functioning in typical community settings in an age-consistent way. Students with motor development impairments produce abnormal muscle tone and may have difficulty sitting and moving. Hearing and vision impairments are very common among children with multiple disabilities such as Deaf-blindness. A lot of students with multiple disabilities have communication impairments and have limited or no speech.

Causes of Multiple Disabilities:In children, early severe impairment of the brain is generally the main cause of multiple disabilities, affecting several areas of the neurological activity (intelligence, motricity, sensory sensitivity). Sometimes, the cause of a student's disability is simply unknown. Studies say that approximately three quarters of all children who have severe intellectual impairment, there is a biological cause which is typically a prenatal bio-medical factor. In other cases, there are specific genetic factors that cause particular tpyes of impairments because of gene or chromosome abnormalities. Some of the main and impairments and disabilties include: -Mental Retardation -Cerebral Palsy -Sever Hypotonia -Motor Control Disorders -Secondary Motor Impairments -Epilepsy -Sensory Impairments -Somatic Disorders -Autism -Deaf-Blindness |
